Uivirnn Starts PATENT @FFTCE JOHN D. VANCE, OF CINCINNATI, OHIO, ASSIGNOR OF ONEIIALF TO JOHN .I. LEBEAU, OF SAME PLAOE.

CAR-COUPLING.

gPE'JlFICATION forming part of Letters Patent No. 307,603, dated November it, 1884:.

Application filed September 24, 1884. (No model.)

To (I/ZZ whom, it may concern.-

Be it known that I, JOHN D. VANCE, of Oincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Oar-Oouplings, of which the following is a specification.

My invention is in the nature of an improvement upon a certain car-coupling for which Letters Patent were granted me June 19, 1883;

IO and it consists of certain novel improvements in said coupling, whereby it is rendered more efficient in practical operation.

In the accompanying drawings, Figures 1 and 2 are longitudinal vertical sections on line I 5 7 y of plan; Fig. 3, a transverse vertical section on line 00 00 of Fig. 4. Fig. at is aplan View; Fig. 5, a portion of a railway-car in plan and Fig. 6, an elevation of couplingpin Similar letters of reference indicate similar parts.

A is a draw-bar, usually of cast-iron; B, the coupling-pin, which may be solid, as shown in Fig. 1, or may be provided with the curved slot 1), as shown in Fig. 6. If the pin is solid as shown in Fig. 1., then the limiting-block G must be used to prevent the pin from jumping out of the draw-bar when the connection between two cars is made, the ram of the link usually being suflicient to throw the pin out of the draw-bar if some means are not provided to limit the upward motion of the pin. The block (3 fits the recess or opening a, Figs. 1 and 4t, and is introduced after the pin B, and secured in position by the tapbolt c. \Vhen the slotted pin 13, Fig. 6, is used, the block 0 and bolt 0 are not required, as will be shown hereinafter.

I) is the coupling-link; E, an arm or lever mounted upon shaft 0, (which turns in bear ings in the forward end of draw-bar, as shown by dotted and full lines of Fig-1,) raises the pin clear of the link when rolled forward.

The general operation of the pin B, link D,

and arm E, so far as the latter is involved in raising the pin B, is the same asin my former patent, and need not be further explained herein. It will be observed, however, that the bearing (0' upon which the pin B turns is l of smaller angle in the present coupling, and

that less slack of link is required in coupling and uncoupling cars.

F is a block provided with an overhanging lip or flange, f, and loosely fitted to recess to", Figs. 2and 3, in which recess said block has a vertical motion limited by the upper and under sides of recess and the flange 1. A projection, c, on the under side of arm E engages with upper surface of block F, (see Fig. 2,) and the lower surface of block F engages with the inner end of the link D in such a manner that when the shaft 0 is rotated backward the projection c presses upon the loose block F and forces the link D downward at its inner end and upward at its outer end, as shown by dotted lines of Fig. 2. This feature permits the link to be varied in altitude to meet the requirements of draw-bars whose months or openings are higher or lower than draw-bar A. The shaft 0 is provided with an eye, a, at its outer end, into which is connected the eye g of shaft G, which shaft passes through hearing 9 attached to side or end of car, and is provided with a handle or arm, by means of which shaft G, and consequently shaft 0, are 7 operated from the outside of car and clear of the railway-trzuzks, frogs, &c., and as the rotation of shaft 0 and arm E forward (or toward head of draw-bar) raises the coupling pin 13 clear of the link D, and the rotation of shaft 0 and arm E in the opposite direction forces block F andlink D downward, it follows that the entire operation. of coupling or uncoupling two cars may be accomplished without going between the cars. The fi6Xlbl6CO11 nection formed by eyes 0 furnishes a universal joint to shafts G- and c for the easy rotation thereofin either direction, and provides for the necessary longitudinal motion of the draw-bar in use. An arm, g, on shaft G, to

which. a chain or rope may be attached, permits the lifting of the pin B from the deck of the car. Vhen the pin B, Fig. 6, is used, the shaft 0 passes through the slot-J) and prevents the pin from jumping out of the draw-bar.

By reference to Figs. 1 and 2 it will be observed that the draw-bar is cored out at a" to permit of a large vertical motion to the inner end of link D when the same is forced down ward by the arm E and block F.

Having described my invention, what I claim is- 1. In combination with draw-bar A and link D, the arm E, provided with a projection, e, 5 and the movable block F, for the purpose and substantially as described.

2. In a car-coupling, the combination, with \Vitnesses: draw-bar A, coupling-pin B, link D, and arm JOHN J. LEBEAU, E, of the flexibly-connected shafts e and G, GHAs. ANDERSON.

IO for the purpose andsubstantially as described.
